[0006] The inventors have discovered that stemmed implants typically have their own instruments for the implantation process. To prepare the bone to accommodate these stems, almost all surgical techniques include a reamer and a broach. However, each implant may have a different set of reamers and broaches depending on the specific length and geometry of the implant. The present disclosure may address the need for a different set of reamers and broaches for each length and geometry of the implant. These instruments can be integrated into a central set of instruments to install all implants designed to include this type of workflow. A modular reamer and broach system is discussed below with reference to Figures 1 through 7.

[0007] FIG. 1 is a schematic diagram of a modular reamer and broach system (system 100). System 100 is delivered to a surgeon to prepare a patient's bone to receive an implant. System 100 can work with multiple different implants. For example, system 100 can prepare a patient's bone to receive advanced fracture implants, revision implants, and limb salvage implants. In some embodiments, system 100 can include multiple reamers (reamer 110) and multiple broaches (broaches 120). Reamers 110 and broaches 120 can be used to prepare a patient's bone for multiple different implants (implants 130).

[0008] The reamer 110 can be configured to ream a portion of bone. The reamer 110 can be modular for reaming a patient's bone in preparation for any implant 130. The reamers 110 can include different sizes. For example, the reamers 110 can include a different diameter than the other reamers in the reamers 110. The different sizes of the reamers 110 can match various sizes of implants 130. The reamer 110 can include a cutting edge 112 and a handle 114. The handle 114 can include a coupling mechanism 118.

[0009] The cutting edge 112 is operable to ream the patient's bone. The cutting edge 112 can be longitudinally extendable. The cutting edge 112 can be removably attached to the handle 114. The cutting edge 112 can have a diameter to match the size of the implant 130. For example, the cutting edge 112 determines the diameter of the ream. In this manner, the system 100 can have multiple different cutting edges 112 to vary the diameter of the ream within the bone. In one embodiment, the cutting edge 112 can be attached directly to the handle 114.

[0010] The handle 114 can allow for handling of the reamer 110 and provides space between the cutting edge 112 and the coupling mechanism 118. The handle 114 can be attached to a tool for applying a force to the handle 114 to rotate the reamer 110 about its central axis. The handle 114 can also be longitudinally extendable. The handle 114 can be removably attached to the cutting edge 112. In embodiments, the handle 114 can include a label or markings indicating the size of the reamer 110 to assist a medical professional in selecting the correct size of the reamer 110.

[0011] The coupling mechanism 118 may be engaged with a ratcheting t-handle. The ratcheting t-handle may be used to rotate the reamer 110 about its central axis. The handle 114 may extend longitudinally from the coupling mechanism 118. As the reamer 110 rotates about its central axis, the reamer 110, and more specifically the cutting edge 112, may engage with the patient's bone to ream the bone. In embodiments, the coupling mechanism 118 may be a quick-release adapter that allows the reamer 110 to be quickly removed from the ratcheting t-handle or any other device that may be used to rotate the reamer 110.

[0012] The broach 120 can be inserted into a patient's reamed bone to prepare the bone's medullary cavity for any implant 130. The broach 120 can be engaged by driving the broach head into the bone, allowing the broach teeth to remove a portion of the bone. The broach 120 can include a coupling mechanism 118, a stem 122, and a number of different broach heads 124.

[0013] Coupling mechanism 118 can attach any of the different broach heads 124 to any of the broaches 120. In some embodiments, coupling mechanism 118 can be engageable with a tool to advance broach 120. In some embodiments, coupling mechanism 118 can extend through different broach heads 124. Coupling mechanism 118 can be a quick-release adapter, allowing broach 120 to be quickly removed from broach heads 124. Coupling mechanism 118 can be integral with stem 122. In some embodiments, coupling mechanism 118 can be a threaded connection, a Morse taper, or any other type of connection capable of withstanding the forces of broach 120.

[0014] The stem 122 may extend longitudinally from the coupling mechanism 118 so that it can be inserted into the patient's reamed bone. The system 100 may include a variety of different sizes of stems 122. For example, each of the different sizes of stems 122 may have a different diameter than the other ones of the stems 122. As the stem 122 extends longitudinally away from the portions of the stem 122 attached to the plurality of different broach heads 124, the stem 122 may taper radially toward the central axis. The taper of the stem 122 may taper the patient's bone to align with the stem of one of the implants 130. The alignment of the patient's bone with the stem of one of the implants 130 may help support the implant 130 after placement in the patient's bone.

[0015] Different broach heads 124 can be configured to fit onto the coupling mechanism 118 of the broach 120 to prepare the patient's medullary canal for one of the implants 130. In some embodiments, the different broach heads 124 can each be configured to prepare the patient's bone for a different type of implant. For example, the different broach heads 124 can be configured to prepare the patient's bone for a limb salvage implant, a revision stem implant, or an advanced fracture implant. The broach 120 can accept the different broach heads 124 such that the different broach heads 124 are removably coupled to the broach 120.

[0016] In some embodiments, system 100 may also include implant 130. In other embodiments, the surgeon may purchase and / or source the implant separately. For example, the surgeon may order the implant as it is to be used and have system 100 prepare each patient for implantation of any of implants 130.

[0017] FIG. 2 shows embodiments of modular reamer 210A, modular reamer 210B, and modular reamer 210C.

[0018] Each reamer 210 (e.g., modular reamer 210A, modular reamer 210B, and modular reamer 210C) can include a cutting edge 212 (e.g., cutting edge 212A, cutting edge 212B, cutting edge 212C) for engaging a patient's bone. In each reamer 110, the cutting edges 212 can be different lengths, diameters, or cutting edges. For example, the different cutting edges can be different cutting types (e.g., blade, grit, diamond, any other surface that can be used to cut a patient's bone, or the like).

[0019] The cutting edge 212A can extend longitudinally from the coupling mechanism 118. The cutting edge 212A can include a plurality of markings 242. The markings can indicate the reaming depth of the modular reamer 210A. In embodiments, the markings 242 can be labeled with an alphanumeric reference code to indicate the reaming depth to the surgeon during operation. The cutting edge 212A can be detached from the reamer 210 so that the cutting edge 212A can be replaced as the cutting edge 212A wears. In an operational embodiment, the extended longitudinal length of the cutting edge 212A can improve reaming efficiency when reaming long passages within bone.

[0020] Modular reamer 210B may include extension 216. Extension 216 can increase the reaming depth of reamer 210B. Extension 216 can be removably attached between cutting edge 212B and handle 214. System 100 may include multiple extensions 216, where each extension 216 can have a different length than the others. In some embodiments, extension 216 may include multiple markings (markings 242). Markings 242 may be molded, etched, marked, or the like on extension 216. The multiple markings 242 can indicate the cutting depth of reamer 210B. In some embodiments, markings 242 can be labeled with alphanumeric reference symbols to indicate the reaming depth to the surgeon during operation. In some operational embodiments, extension 216 can enable modular reamer 210B to ream deeper passages within bone.

[0021] The modular reamer 210C can have the extension 216 removed so that the cutting edge is directly coupled to the handle 214. The handle 214 can include a plurality of markings (markings 242). The markings 242 can be molded, etched, or the like on the handle 214. The plurality of markings 242 can indicate the cutting depth of the reamer 210C. In embodiments, the markings 242 can be labeled with alphanumeric reference codes to indicate the reaming depth to the surgeon during operation. In an operational embodiment, the modular reamer 210C can be an efficient reamer for short passages. Additionally, the length of the modular reamer 210C can reduce the cost of the modular reamer 210C because less material is used to manufacture the modular reamer 210C.

[0022] Each reamer 210 may include a coupling mechanism 218. The coupling mechanism 218 may enable the reamer 210 to be engaged with a tool such that the reamer 210 may be rotated about a central axis of the reamer 210.

[0023] FIG. 3 illustrates an embodiment of a system 300 that includes one or more modular broaches 320 and several different broach head embodiments (different broach heads 324).

[0024] The modular broach 320 can be inserted into a patient's reamed bone to prepare the bone canal for any implant. The modular broach 320 can include a stem 322. The stem 322 can extend longitudinally from a coupling mechanism 318. A mounting portion 326 can be defined within the coupling mechanism 318. The mounting portion 326 can receive any of the different broach heads 324. The stem 322 and the different broach heads 324 together can prepare the bone to receive the implant.

[0025] System 300 may include broach head 324A. Broach head 324A may be a limb salvage broach. Thus, broach head 324A may prepare reamed bone for implantation of a limb salvage implant. Broach head 324A may be removably attached to a tool via coupling mechanism 318 for advancing stem 322 and broach head 324A.

[0026] System 300 may include broach head 324B. Broach head 324B may be a revision broach. Thus, broach head 324B may be used to prepare reamed bone and implant a long, identity revision broach. Broach head 324B may be removably mounted to a tool for advancing stem 322 and broach head 324B.

[0027] The system 300 may include a broach head 324C. The broach head 324C may be a fracture / revision broach head. As such, the broach head 324C may be used to prepare reamed bone for implantation of the fracture / revision broach head. The broach head 324C may be removably mounted to a tool for advancing the stem 322 and the broach head 324C.

[0028] FIG. 4 is a schematic diagram of a modular reamer (reamer 410) for reaming bone 10. The reamer 410 may include cutting edges 412 and a coupling mechanism 418. In an operational embodiment, the coupling mechanism 418 may be attached to a tool that rotates the reamer 410 about a central axis so that the cutting edges 412 engage the bone 10. As shown in the drawing, a surface of the bone 10 may be resected to prepare the bone 10 to receive the reamer 410. The reamer 410 may ream the bone 10 with an axial force along the longitudinal axis of the bone 10. The reamer 410 may prepare the bone 10 and ream the bone 10 to receive a broach. In an embodiment, one or more of the reamers 410 may be used to vary the depth reamed into the bone 10.

[0029] FIG. 5 is a schematic diagram of a modular broach (broach 520) for preparing bone 10. As shown in FIG. 5 , broach 520 may include a stem 522 and one of a number of different broach heads (different broach heads 524). Stem 522 may taper radially inward as it extends away from a coupling mechanism 518 thereon. Coupling mechanism 518 may engage with different broach heads 524 to removably couple the different broach heads 524 to the stem 522. In an operational embodiment, broach 520 may be inserted into a portion of bone 10 reamed by reamer 410. By attaching a tool attached to coupling mechanism 518 to broach 520, broach 520 may be advanced to remove bone 10. As mentioned above, the broach 520 can use different types of different broach heads 524 to prepare the bone 10 for different types of implants.

[0030] 6 is a schematic diagram of an implant 630 assembled within bone 10. In the embodiment of FIG. 6, implant 630 may be an advanced fracture implant. In another embodiment, implant 630 may be a limb salvage implant, a revision implant, or the like. In an operational embodiment, a system (e.g., system 100, system 200, or system 300) may be used to prepare bone 10 for each of the different types of implants 630 by using appropriate reamers and broaches to prepare bone 10 for implant 630.

[0031] FIG. 7 is a block diagram illustrating a method 700 in accordance with at least one embodiment of the present disclosure. Method 700 may be a modular reamer and broach system method. More specific examples of method 700 are discussed below. The steps or processes of method 700 are shown in a particular order for convenience. Many of the processes discussed can be performed in a different order or in parallel without substantially affecting other processes. The discussed method 700 may include processes performed by multiple actuators, devices, or systems. It should be noted that a subset of the processes discussed in method 700 may be attributed to a single actuator, device, or system, which may also be considered separate and independent processes or methods.

[0032] In step 705, method 700 may include retrieving an implant commensurate with the patient's bone condition and size. For example, a surgeon, nurse, medical technician, or similar may retrieve an implant to treat the patient's condition. A medical professional may retrieve a limb salvage implant, a revision implant, or a fracture implant, depending on the patient's injury needs. Furthermore, the size of the implant may be selected depending on the size or diameter of the patient's bone.

[0033] At step 710, the method 700 may include obtaining a reamer that corresponds to the size of the obtained implant. Medical staff may obtain a reamer of an appropriate size to match the selected implant. For example, the size or diameter of the reamer may be equal to or slightly smaller than the implant.

[0034] In step 715, the method 700 may include reaming a portion of the patient's bone. As discussed in connection with FIG. 4, a reamer may ream the bone to prepare it for the broach.

[0035] At step 720, method 700 may include obtaining a broach that corresponds to the size and type of implant obtained. The broach may be selected by the medical professional based on the type of implant obtained. Further, the size of the broach may match the size of the implant selected by the medical professional.

[0036] At step 725, the method 700 may include preparing the medullary cavity of the patient's bone. A broach can be used to mechanically remove bone. For example, a broach tooth arrangement is advanced to scrape and abrade the bone in the medullary cavity to prepare the bone for the implant.

[0037] At step 730, the method 700 may include inserting the obtained implant into the patient's bone. In embodiments, the implant may be inserted into a prepared portion of the bone.
